IMPROVEMENT IN HARROWS.

Specication forming part of Letters Patent N o. 192,942, dated July 1l),1877; application led May 17,1877.

To all whom t may concern Be it known that I, WILEY G. P. SHARP, ofWartrace, in the county of Bedford and State of Tennessee, have inventedcertain new and useful Improvements in Harrows; and I do hereby declarethe following to be a fu1l,clear,V

' two inclined side beams, A A, united at their front ends with the poleor draftbar B between them. The rear ends of the side beams A are spreada suitable distance apart, and connected by a cross-bar, C, making atriangular frame of any suitable dimensions. In this frame are insertedrake-teeth D D, as shown, said teeth being formed at their upper endswith shanks 2l, to be passed through holes made in the frame for thatpurpose.Y `Each tooth `has front and rear cutting-edges a a, and is madethicker in the center, taperingto a point, b-or, in other Words, thetooth is diamond-shaped in its cross-section.

In suitable boxes h h, von the under sides of the side beams A A, neartheir rear ends, are placed the journals i t' of a roller, G, which islalso provided with similarly-shaped The teeth D of the roller are setinto the same in rows, and alternating substantially as shown. l

On the under side of the rearcross-bar C of the frame are securedforwardly-projecting clearers m m, between which the rollerteeth D passduring the revolution of the roller, to clar the teeth of all adheringearth, weeds, trash, te. The two side clearers m m are projected stillfarther forward, to come alongside the ends ofthe roller near thejournals t, to prevent any trash, &c., from winding around theroller-journals.

J J are the handles 'of the harrow, the front, ends of which are beamsA, and their rear ends supported by means of a round or cross-bar, I,passing through them and through upright standards I I', secured to therear -bar (l of the harrow frame. 4

P represents an axle, provided with a wheel, R, on each end. This axleis placed in vertical staples or slotted standards S S, projectingupward from the side beams A A of the barrow-frame, the axle beinggrooved on front and rear for the passage of the. arms of the staples orstandards. To this axle is connected a lever, L, the front end of whichis, by a metal strap, p, connected with a rod,

l n, between the side beams A A of the Ahar-V row-frame, and the rearend of the lever projects Vbetween the standards I', and may be lockedonan upright stan'dard, H, secured to the cross-bar C between thehandle-standards Il I. This latter standard H has at the top a shoulder,s, and near the bottom a reversed shoulder, t. f Y

By'leaving the lever L free `at its rear end the wheels R will simplyrun on the ground, with nothing but their own weight, while by raisingthe rear end of the lever, and placing the same on the shoulder s of thestandard H, the axle Pand wheels B R are elevated so that the wheelswill not touch the ground, Aand the weight of said axle and wheels -isthus added to the weight of the harrow.

By depressing the rear end of the lever L I and placing the same Aunderthe reversed shoulder t, the entire harrow is raised out of the groundand suspended below the axle, the parts being so arranged that theharrow` will then be balanced. I n this position the harrow is easilymoved to and from the liield, orA

from one eld to another.

In operation, the barrow is easily raised,

by means of the lever L, to pass obstructions or for clearing purposes,when necessary.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is

In a barrow, the combination of the triangular frame A, having therevolving roller secured to the side G journaled in its rear e videdwith teeth, handles wheels R, H, both the frame and raised at th shown.

slotted standards S, and standard e same time, substantially asv nd, andboth prohave hereunto set my hand this 4th day ot J, lever L, axle P,lllay,r 1877.
